John Alford / Ontario Co Ny / 1820

I'm trying to find the parents of my gggreatgrandmother , Ellen A. Alford Hastings Hunter. She was born about 1816 in NY. Her father was John Alford , born possibly in MA . Her mother , name unknown , may have born in NJ . I think that this John Alford who appears in the 1820 census could be her father . One of her sons from her first marriage to John Adam Hastings was Zalmon Rice , born about 1836 in NY. I've reached a brick wall in this search . Any information on the Alford , Hastings , or Rice family , who were all in Ontario Co at this time would be greatly appreciated.
